General Principles
Definition
A trachelectomy is performed to remove a cervical stump. The stump is the remnant of the uterus following a supracervical hysterectomy.
Differential Diagnosis
Pelvic mass
Cervical neoplasia
Prolapsed fallopian tube
Gartner duct cyst
Vaginal polyps
Vaginal adenosis
Vaginal endometriosis
Imaging and Other Diagnostics
Patients with abnormal vaginal bleeding require ultrasound imaging. Consider obtaining a CT scan if a pelvic mass is suspected.
Cervical cancer screening is required preoperatively.
Preoperative Planning
The route of surgery depends on the indication for trachelectomy, surgeon’s experience and comfort, the presence of comorbidities, and the need for concomitant procedures. The preoperative planning for a vaginal trachelectomy begins with a thorough history and physical examination. The surgeon should pay particular attention to the degree of prolapse, the presence of a pelvic mass, adnexal tenderness, and whether the cervix is mobile. A laparoscopic approach should be considered if the patient has unexplained pelvic pain or suspected endometriosis, or if there is an adnexal/pelvic mass requiring removal. Counseling should include the risk of conversion to laparotomy, independent of a minimally invasive approach.
Confirm the patient’s cervical cancer screening is up-to-date.
Patients with significant medical comorbidities should also undergo preoperative clearance.
Perform thorough counseling and discuss the risks, benefits, alternative, and different routes of surgery. Obtain a signed, informed consent.
Regardless of the surgical route, a trachelectomy is a clean-contaminated procedure and a prophylactic antibiotic should be administered prior to incision. We commonly use a first- or second-generation cephalosporin.
Surgical Management
The most common indications for trachelectomy are pelvic organ prolapse, pelvic mass, abnormal cytology, bleeding, and pain. Trachelectomy is a relatively safe and effective procedure. Patients should be counseled on the risk of bleeding and injury to the urinary tract or bowel.
Positioning
Positioning for a vaginal trachelectomy is similar to positioning for a vaginal hysterectomy (see Chapter 8.5, Vaginal Hysterectomy). The patient is placed in the dorsal lithotomy position using candy cane or Allen stirrups. The use of Allen stirrups is preferred in cases where there is a high likelihood of converting to an abdominal procedure or if there is a need for concomitant laparoscopy.
Positioning for a laparoscopic/robotic trachelectomy is similar to the positioning for a laparoscopic/robotic hysterectomy. The patient is positioned in the dorsal lithotomy position using Allen stirrups with the patient’s arms secured to her sides (see chapter on Diagnostic Laparoscopy, Patient Positioning).
Approach
An abdominal (open, laparoscopic, or robotic) approach is preferred when the patient complains of pelvic pain or endometriosis is suspected. In addition, if a pelvic mass is appreciated on examination or imaging, an abdominal approach is mandatory.
A vaginal approach is preferred in patients with significant comorbidities, when abdominal exploration is not required or when the trachelectomy is performed due to prolapse.

Preparation
Prepare and drape the patient’s vagina, perineum, and lower abdomen.
Insert a Foley catheter and drain the bladder.
Tenaculum placement
Place a weighted speculum or retractor in the vagina to expose the cervix.
Grasp the cervix with a single-tooth or Jacob’s tenaculum and gently apply downward traction.
Circumferentially inject a vasoconstrictor (lidocaine with epinephrine or dilute vasopressin) at the cervicovaginal junction.
Incise the cervicovaginal junction and advance the bladder
Using a number 10 bladed scalpel or monopolar instrument, circumferentially incise the cervicovaginal junction.
Using curved Mayo scissors, dissect the vagina and the bladder off the cervix anteriorly and posteriorly.
Enter the posterior cul-de-sac
Carefully palpate the posterior cul-de-sac.
If no adhesions are noted and if entry into the peritoneal cavity is not required, place a Heaney clamp extraperitoneally above the cervical stump bilaterally. Then excise the cervix with a scalpel or Mayo scissors.
If entry into the peritoneal cavity is required, deflect the cervix anteriorly, grasp and tent the tissue, and sharply enter the posterior cul-de-sac with Mayo scissors.
Then palpate the posterior cul-de-sac to assess for bowel adhesions.
Transect the uterosacral ligaments and enter the anterior peritoneum
Use a Heaney clamp or a vessel sealing device to clamp and divide the uterosacral ligaments. If a Heaney clamp is used, suture ligate the pedicle with a No. 0 polyglactin 910 (Tech Fig. 10.1).Stay updated, free articles. Join our Telegram channel
